A short time ago someone posted (and I think it was in here) a useful write up on a series of calibration cubes. Each printed with the same filament but with different settings. I meant to bookmark it for reading later, didn’t. Can anyone remember it or know where it is please? Thanks

I do not know where your post is, but if you + 1 it or you comment on it, that will help you find it in previously read under the bell. You could also privately share with yourself.

If not in this community, it may have been someone from your circles or the rep rap community. I think there might also be a delta community. The maker communities sometimes post about 3d printing too.
